Suppose you have data that shows that 12% of athletes test positive for steroids. you also know that 11% of athletes test positive for steroids and actually use steroids. what is the probability that an athlete uses steroids, given that he tests positive? .

the probability is: 0.92

Step-by-step explanation:

let the total number of athletes be 'x'. and let 'P' denotes the probability.

let A shows the event that a athlete test positive for steroids.

let B shows the event that athlete use steroids.

as given in the question 12% of the athletes test positive for steroids=0.12 x.

⇒  P(A)=0.12 x

also we know that 11% of the athletes test positive for steroids actually use steroids=0.11 x.

⇒P(A∩B)=0.11 x

Now we are asked to find the probability that an athlete uses steroids, given that he test positive that is we have to find

Hence, the probability that an athlete uses steroids, given that he tests positive is 0.92.

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
